Specific embodiment
It summarizes
The embodiment of the present invention being described below is provided in the remote of medical probe (for example, catheter sheath)
End is promoted via cerebrovascular system to engage the system and method for tracking the distal end when brain grumeleuse.The distal end of probe generally includes to protect
The distal end of set and the distal end of axis, wherein in various embodiments, different elements is assemblied in the far-end and/or axis of sheath
Far-end.As an example, the embodiments described herein relates generally to catheter sheath.
In an exemplary embodiment, it is removed in brain by being inserted into and being advanced in the cerebrovascular by clot removal device
Grumeleuse, such as grumeleuse remove bracket.In general, (being changed by sliding the sheath of conduit between grumeleuse and wall comprising it
Sentence is talked about, and grumeleuse is penetrated) grumeleuse is removed, until sheath crosses grumeleuse.Then so that bracket is passed through sheath, and then leaving
When sheath, extend to capture grumeleuse.The grumeleuse for then taking out sheath and bracket and being captured.In some embodiments, it protects
It covers the nearside in its distal end and is equipped with balloon-expandable, wherein balloon inflation, can to increase the distal end of sheath to anchor sheath
Cross or penetrate penetration power used in grumeleuse.
In some embodiments, locating pad neck ring is placed around the neck of patient.Locating pad includes being configured to suffering from
The magnetic field generator in magnetic field is generated in person head.Magnetic position sensor is assemblied in the far-end of sheath.In response to the magnetic sensed
, position sensor generates the position signal of its position in brain of instruction.Processor receives position indicative signal and uses it
Estimate the position of sheath distal end in brain.
During locating pad neck ring is configured to Position Tracking Systems, by pad neck ring since head movement is mobile come automatically
The head for compensating patient is mobile.In one embodiment, additional reference position sensor can be attached to the forehead of patient
To generate the mobile additional location signal in instruction head.Latter position signal can be used in processor, based on indicated
Mobile automatic its estimation to sheath distal end position of compensation (that is, correction) in head.In one embodiment, reference sensor packet
Include magnetic position sensor.
In one embodiment, the magnetic estimated location of sheath distal end and brain medical image (such as show that the CT of grumeleuse schemes
Picture) registration, so that the distal end of sheath be allowed to be presented on image related with the grumeleuse being imaged.If desired, tracking allows
The position of sheath distal end is corrected to meet the anatomical structure being imaged, such as correctly to show included in endovascular sheath
Distally.
In some embodiments, instruction of the sheath distal end presented on the image relative to the position of shown brain grumeleuse
Grumeleuse is crossed in distal end for verifying (that is, instruction) sheath.In some embodiments, the distal end for receiving sheath
When through crossing the instruction of grumeleuse, the clot removal device for being mounted on axis far-end is unfolded to remove grumeleuse.
Although radioscopy can be used for tracking probe when probe is advanced to grumeleuse, fluoroscopic examination keeps patient sudden and violent
Be exposed to relatively large dose ionization X-ray radiation and a large amount of contrast agent.Doctor is also repeated exposure to X-ray radiation, X-ray spoke
Penetrating may accumulate during many regulations to undesirable level.
Disclosed technology for tracking probe while being advanced to grumeleuse, and optionally during removing grumeleuse with
Later, the needs to the radioscopy of potential danger are eliminated.In addition, disclosed technology can be eliminated to large and expensive
Conduit insertion room needs, to adapt to the image mode based on X-ray.
Brain grumeleuse removes the description of position sensor and locating pad neck ring system on sheath
Fig. 1 is the schematic figure of the cerebrovascular positioning control system 20 catheter-based of embodiment according to the present invention
Solution.System 20 is by the reference system and use of the CT image of patient 32 (as citing, being assumed to be herein e.g., including perspective CT image)
In the reference system alignment of the electromagnetic tracking system 23 of the Magnetic Sensor of tracking patient's intracerebral.
In system 20, the locating pad 24 for constituting electromagnetic tracking system is implemented as the neck placed around the neck of patient 32
Circle, and it automatically compensates for patients head's movement.Locating pad 24 includes magnetic field generator 26, and the magnetic field generator is relative to trouble
The head of person 32 is secured in position and in the region 30 that is transferred to sine alternating magnetic field where the head of patient 32.Console 50 passes through
By 25 electric drive generator 26 of cable.In one embodiment, before by the way that reference position sensor 21 is attached to patient
Volume provides being further compensate for for head movement.Console 50 is configured to receive via cable 27 from reference position sensor 21
Signal.
For example, the generator 26 of locating pad 24 is arranged to approximate circle shape around the neck of patient 22.However,
Any suitable alternative configuration of the generator of locating pad 24 can be used.
The proximal end of conduit 28 is connected to by the catheter controller handle 29 that the doctor 54 as operating system 20 keeps.Control
The permission doctor of device handle 29 promotes and conduit 28 in the brain that navigates, such as the inlet point 22 at the thigh artery for passing through patient 32.Doctor
Teacher 54 comes the distal end of catheter navigation 28 using the position signal of the magnetic position sensor from the distal end for being assemblied in conduit 28, as follows
What face further described.Console 50 receives position signal via cable 19, which is connected to conduit 28 for handle 29.By adding
The Biosense Webster production in the city Li Funiya Zhou ErwanSystem use be similar to system as described herein with
For finding position and orientation of the magnetic field position sensor in the brain area domain by magnetic field radiation.
The element of system 20 including generator 26 is controlled by system processor 40, the system processor include with one or
The processing unit of multiple memory communications.Processor 40 is mountable in console 50, which includes operational controls 58, should
Operational controls generally include keypad and/or indicator device, such as mouse or trackball.Doctor 54 uses the operation on handle 29
Control piece is interacted with processor on time in matching for execution system 20.During registration process, brain point is presented on screen 56
Image 59.After registration process, the distal end of conduit 28 is advanced to brain localization 60 using operation controller by doctor 54, at that
In grumeleuse block artery.The result of conduit tracking regulation is presented in processor on screen 56.
Processor 40 carrys out operating system 20 using the software being stored in memory 42.For example, software can be electronically
Processor 40 is downloaded to by network, or alternatively or in addition to this, which can be provided that and/or be stored in non-transitory
On tangible medium (such as magnetic memory, optical memory or electronic memory).
Processor 40 operates the magnetic flux generator 26 of locating pad 24 using software and other function.As described above, occurring
The sine alternating magnetic field of different frequency is transferred in region 30 by device, the head including patient 22, and is felt in sensor 32
Induction signal.Processor analyzes signal to export position and the orientation value of sensor, and therefore exports the position of the distal end of conduit 28
